Wierd faint whine when cruising 5-20mph
Whenever im driving through parking lots i hear a faint whine reflecting off the other cars/wall and it sounds like a tiny mouse crying away.
I've never experienced this before, first i thought it was my tires, but it happens in all types of pavements so i doubt its that. I checked inside the engine bay and dont hear anything in idle, its only when moving slowly.
Anyone else?

maybe check your brakes, they could be low and scrapeing, or possible loose/rattleing heatshields or exhaust hangers. Have a friend hang out the window(while driving slow!) and listen to see if its coming from front, back, or middle, that should point you to the general area.

Possibly power steering pump. Check the fluid for it. even if there is fluid in it still check it... here is a tip take a very long screw driver put it up to the pump housing and put your ear on the handle. The sounds will travel through the screw driver and you will be able to pinpoint it.. with the engine running of course. and make sure you dont get it in the way of moving pulleys and belts. that tip can be dangerous if your not careful. I am not responsible for whatever happens with that trick

Exactly my thought. The "squealers" will drag on the rotor lightly and make an annoying noise just like the crying mouse description. In my experience I can only hear it when I drive past something that reflects the sound.

BUT if its a faint whine like you described in the title...I'd probably say maybe your water pump is starting to go. The first signs that my water pump was going out was the faint whine under load and small drops of coolant visible on my driveway. To me, it sounded like when your power steering lacks some fluid. But if it was the power steering you may only hear it when you turn the wheel. Just another thought should the brakes check out fine.
It would be easier to check your brakes and go from there.

I'll have to agree with this based on OP's comment regarding the crying mouse description.

Ok, its definitely coming from the front. Usually only appears after a days drive and driving slow through the neighborhood to get home.
Here's a sound clip. Not the best because i recorded it right away with my mp3 player because it only starts squealing every once and a while.

It's the inner dust seal on the hub that's dried up. If you back the axle out of the hub a bit and spray some lube on the inner seal it goes away. I took my axle's out to rebuild the boots and discovered the dried up area. You can clearly see the highly polished, almost burnt glaze on the axle hub where the seal was making contact. Greased it up and the noise has never come back.
Seemed mine was only the drivers side that made the noise, but both side were very dry.

What kind of seal are we talking about here, rubber or metal? Its not something that needs replacing is it? My tires are solid and dont make a "marble" noise when spinning so i doubt its the wheel bearing. Hopefully your right and ill see it when i replace my pass. axle. Just replaced my driver 3 weeks ago and now my pass. side boot tore.
Here's a better video of my camera attached to my mud flap. Lens was covered in tape so you wont see anything, but you can hear it. Gets louder towards mid-end.

I've been trying to find out what that noise was for months. I've been to car shops and even the dealership and nobody can figure out exactly what it is. Thank you for figuring it out. That noise has been driving me crazy. What kind of lube did you use to get rid of the noise?
